We implemented such a scheme with our peer to peer file sharing scheme a few years ago (combined with NAT whole punching). What you are trying to do is bidirectional file replication with dynamic IPs. I am assuming that you don't care about concurrent writes to the files (because unless you have a distributed lock manager in addition to the RVP, the content of the files will not be deterministic).
